I'd be pretty excited if the C's could get Porzingis for #3, Crowder, and a future first (either Boston's 2018, the Clipper's pick, or the Memphis pick). Then go as hard after Hayward as possible.
IT, Avery, Hayward, Horford, Porzingis starting with Smart, Jaylen, and Zizic as the major rotation guys. That's a good looking lineup and we still have Brooklyn's pick and LA's pick next summer.
I'm dubious the Knicks are actually serious about trading Porzingis but who knows with that organization.
